NDT3462 ULTRASONIC TESTING II COURSE PROCEDURE


NDT 3462 ULTRASONIC TESTING II

3 Credit Hours

Student Level:

This course is open to students on the college level in either the Freshman or Sophomore year and to area high school vocational students.

Catalog Description:

NDT3462 - Ultrasonic Testing II (3 hrs.)

This course is a continuation of Ultrasonic Testing I with emphasis on advanced theory and practical skills required in the application of ultrasonic evaluation methods. The course is designed to meet certain Nondestructive Testing Level II requirements in accordance with A.S.N.T., SNT-TC-1A, & NAS-410.

Course Classification:

Lab

Prerequisites:

NDT3461 Ultrasonic Testing I or instructor approval.

Controlling Purpose:

This course is designed to impart applied advanced methods and applications of ultrasonic inspection.

Learner Outcomes:

Upon completion of this course the student will be able to:

  1. List and describe the principles of wave propagation.
  2. List and describe and demonstrate the ability to locate and sizes defects.
  3. Distinguish between types of test methods.
  4. Choose a specific test procedure and follow it in inspection of a material.
  5. List and describe the variables affecting a shear wave inspection.
  6. Apply an understanding of the ultrasonic method to defect location and evaluation using contact and immersion inspections.
  7. Correctly apply safety attitudes and procedures associated with ultrasonic testing that will insure a safe work place environment.

Unit Outcomes for Criterion Based Evaluation:

The following outline defines the minimum core content not including the final examination period. Instructors may add other material as time allows.

UNIT 1: Properties of Sounds in an Object

Outcomes: Upon completion of this unit, the students will be able to successfully determine the content of an object by evaluating the return signals.

  • Assess return signals from a material and determines size and location in relationship to a known defect standard.
  • Evaluate defect location by application of calculations.

UNIT 2: Wave Mode and Generation

Outcomes: Upon completion of this unit, the students will be able to successfully list and demonstrate wave mode generation.

  • Apply calculations to develop a shear wave in a material using immersion inspection.
  • Apply calculations to determine a shear wave in a material when the incident angle is given using water as a coupling medium.

UNIT 3: Selection and Set-Up of Equipment

Outcomes: Upon completion of this unit, the students will be able to successfully select and calibrate two pieces of ultrasonic equipment.

  • Demonstrate the ability to calibrate a five and ten inch shear wave screen.
  • Demonstrate the ability to calibrate a surface wave mode on steel.

UNIT 4: Selecting the Correct Method of Inspection

Outcomes: Upon completion of this unit, the students will be able to successfully locate and select the correct transducer instrument combination.

  • Modify existing plan of inspection when required to change transducers yet produce the same inspection results.
  • Given a material, defect size and location, apply knowledge to determine the correct inspection method.

UNIT 5: Limiting Variables

Outcomes: Upon completion of this unit, the students will be able to successfully list and describe variables that affect shear waves.

  • Use calculations to limit variables, list those that could be determined before the inspection begins.
  • Categorize variables that affect ultrasonic inspection in a list from the most problematic to the least problematic.

UNIT 6: Standard Reference Books

Outcomes: Upon completion of this unit, the students will be able to successfully demonstrate the use of reference blocks.

  • Demonstrate the use of area amplitude and distance amplitude blocks when setting up a DAC.
  • Demonstrate the use of the IOW and the IIW blocks when using shear wave inspection.
  • Demonstrate use of the resolution block.
  • Demonstrate use of the mini-angle beam block, the DSC, and the SC block.

UNIT 7: Locating Defects with Shear Waves

Outcomes: Upon completion of this unit, the students will be able to successfully calculate, analyze and predict the location of defects in a material.

  • Calculate depth and defect location when using shear wave inspection.
  • Calculate size of a defect when inspecting with shear waves.

UNIT 8: Reflecting Characteristics of Sound

Outcomes: Upon completion of this unit, the students will be able to successfully calculate the amount of sound reflected at a defect or interface.

  • Compute the amount of sound returned from a defect and equate it with size and type of defect.
  • Compute the amount of sound returning to the transducer if no defect is present.

UNIT 9: Sizing and Mapping of Defects

Outcomes: Upon completion of this unit, the students will be able to successfully illustrate the location of defects.

  • Diagram sound traveling in a part, showing all areas of reflection and refraction.
  • Assess the returning signal then draw a schematic of the part showing location and orientation of defect or defects.

UNIT 10: Acceptance Standards

Outcomes: Upon completion of this unit, the students will be able to successfully list standards used in ultrasonic inspection.

  • Interpret D1.1 ultrasonic inspection listing size and amount of defects allowed in the weld inspected.
  • Using the API Code. Create an inspection of a pipe sample. List and describe all defects located in the inspection.

UNIT 11: Reports and Part Identification

Outcomes: Upon completion of this unit, the students will be able to successfully write and explain defect location in a report.

  • Write a standard report on ultrasonic inspection per the requirements of D1.1.

Projects Required:

Refer to Syllabus

Textbook:

Contact Bookstore for current textbook.

Attendance Policy:

Students should adhere to the attendance policy outlined by the instructor in the course syllabus.

Grading Policy:

The grading policy will be outlined by the instructor in the course syllabus.

Maximum class size:

Based on classroom occupancy.

Course Time Frame:

The U.S. Department of Education, Higher Learning Commission and the Kansas Board of Regents define credit hour and have specific regulations that the college must follow when developing, teaching and assessing the educational aspects of the college.  A credit hour is an amount of work represented in intended learning outcomes and verified by evidence of student achievement that is an institutionally-established equivalency that reasonably approximates not less than one hour of classroom or direct faculty instruction and a minimum of two hours of out-of-class student work for approximately fifteen weeks for one semester hour of credit or an equivalent amount of work over a different amount of time.  The number of semester hours of credit allowed for each distance education or blended hybrid courses shall be assigned by the college based on the amount of time needed to achieve the same course outcomes in a purely face-to-face format.
